While many studies that analyse the mechanisms of content propagation in social media exist,
how to model the effect users' emotional and cognitive state or traits on the propagating malicious content is unclear, especially in light of the significant contribution of their cognitive limits [1]}, [2]}, [3]}.
Important cognitive factors are users' limited attention and error-prone information processing [1]}. Emotional features of the messages may worsen this [5]}, [6]}. Moreover, the lack of non-verbal communication and limited social presence [7]}, [8]}, [9]} often exasperates carelessness and misbehaviours, as the users perceive themselves as anonymous [10]}, [11]}, and do not feel judged or exposed [12]}.
